With the rising demand for improvements in efficiency and power availability, efforts are underway to incorporate higher voltages into the electrical systems of heavy-duty commercial motor vehicles. Throughout this effort, it is important that safety, reliability, and compatibility with equipment currently in use, be maintained. This paper, developed by TMC’s Electrical/Electronic Systems Task Force, under the auspices of the Council’s Future Truck Committee, serves to further outline these expectations.

The Future Tire Durability and Reliability Task Force — working under the auspices of TMC's Future Truck Committee — was tasked with exploring and identifying key factors related to the adoption of zero-pressure tires in commercial transportation service. Accordingly, the Task Force developed this position paper to define future features and expectations for zero pressure commercial tires in terms of product performance, maintainability, reliability, durability, serviceability, environmental and educational issues. This document provides the industry with an overview of what will be necessary for trucking companies to integrate this new technology into their fleets.

The application of hydrogen fuel cell technology to commercial trucks has received a great deal of attention lately, especially following the announcement of at least one manufacturer’s plans to introduce a hydrogen-hybrid electric model for purchase by the year 2020 and a second OEM’s planned test at the Port of Los Angeles. As might be expected, this interest has prompted many questions by both fleet and supplier professionals. TMC's Future Truck Committee charged its Future Alternate Propulsion System Task Force to explore the issue and this paper represents its findings as to whether the technology is ready for commercial use, using a “pass/fail” scale.

Significant opportunities exist to collect or harvest energy using systems or technology on the trailer for improving the energy efficiency of the vehicle combination. Two such sources, solar
energy collection and regenerative braking are being investigated in earnest and are in the early stages of commercial development. The purpose of this paper is to facilitate increased performance and energy efficiency for trailers. Additionally, this paper offers goals for energy efficiency improvement related to the design and operation of semi-truck trailers to encourage and accelerate development of appropriate technology.

Today’s heavy-duty truck manufacturers are increasing their focus on more efficient management of all types of energy in commercial vehicle (e.g., combination vehicle, straight truck, etc.). This position paper explores industry efforts at attaining alternate energy sources and what steps should be taken to implement such alternatives successfully for commercial vehicle operations.
TMC believes the next step in vehicle energy conservation is to investigate the usage of the fuel energy once it is burned and develop strategies for efficient recovery and subsequent usage where possible and feasible. At the same time, this effort should include using ‘free’ energy, specifically solar, as part of the overall energy mapping process.
The time is now to begin laying out an electrical system architecture that will accommodate the energy efficient tractor and trailer of the future. TMC's study groups and task forces should play a leading rolle in developing this architecture, working with other industry groups and organizations as needed.

The ability to refine wheel-based road speed calculations through the adjustment of wheel rotations per mile via global positioning satellite (GPS) input is a desirable feature that does not yet exist for heavy-duty commerical motor vehicles (CMVs). This technology, which would dynamically adjust rotations per mile to account for tire wear, could improve speedometer accuracy and fuel economy reporting (as reported by the engine electronic control unit or (ECU). It also has the potential, if wheel-end sensors are employed, to report current remaining tread depth and the need for tire replacement due to wear. This technology would compare vehicle distance travelled as measured by both a GPS-enabled device and the vehicle ECU, and should a reasonably significant difference exist, the ECU’s “wheel rotations per mile” parameter would be automatically adjusted accordingly, to compensate for tire wear.

Traditional methods for both pre- and post-trip inspections have existed for decades with few changes or improvements. Traditional tools and technology limit inspection effectiveness, add time to both the inspection and reporting, and contribute to the potential for errors and miscommunication of the resulting data. This paper explores technologies that may increase the efficiency of pre- and post-trip trailer inspections and provides a vision for future development of technologies and systems for that purpose.

This Position Paper offers several recommendations regarding the development and implementation of automated driving and platooning systems. It should not be viewed as an endorsement of automated driving and platooning systems. For a comprehensive review of the intensive activity associated with the development and introduction of Automated Vehicles (AVs) and the potential issues and opportunities they pose for the trucking industry, refer to TMC’s Information Report IR 2015-02, Automated Driving & Platooning: Issues & Opportunities.

The issue of driver distraction in Class 7-8 commercial vehicles has two major components. First, the vehicle often contains multiple information/warning devices and systems which can be confusing and distracting. Second, interactive electronic devices and systems can be added or brought into the driver compartment. The compounding effect of excessive information, warnings and alarms within the interactive electronic devices can result in high levels of driver distraction. Accordingly, TMC’s Future Truck Committee urges the development of industry-wide guidelines for the installation and use of these devices in Class 7-8 commercial vehicles. Until these industry-wide standards can be established, TMC recommends manufacturers, suppliers, and fleets take a common sense approach to these devices to minimize driver distraction.

360° Driver Awareness Expectations.
Vehicle crashes are greatly impacted by a driver’s knowledge of what exists around his or her vehicle. The term “360° Driver Awareness” describes technologies and devices that improve safety by increasing a driver’s knowledge of what is around his or her vehicle. This paper serves as a request for manufacturers and suppliers to share their plans for products that will be marketed within the next 10 years (or as soon as possible) to allow equipment users to better assess and implement the technology in their operations. It also serves to outline equipment user expectations for such technologies as used in commercial vehicle operations.
